Description

This beetle is bright green-blue and red-brown in color.[2] The adults are 5.6–7.7 mm long, with females larger than males.[3]

Biology

This beetle forms aggregations of several individuals, often with beetles of the genus Brachinus.[2] When disturbed it releases a volatile that contains undecane.[2] Its coloration may be aposematic mimicry of the similarly colored Brachinus beetles it lives with, which emit a much more powerful antipredator volatile mix.[4]

gollark: It's your fault for being mugged. You were practically ASKING for it by having money.
gollark: Especially because accidents are a thing.
